When I put cams and cam gears in do I need to tune the A/F. I know I need to adjust the cam gears, but do I need to buy to do a/f tuning. Currently I have several mods with the p2 flash. What do you guys think?

 

I don't know anything about the P2, I would call them 1st and make sure the car will idle with the cams and there flash.

 

THey offer their cams with a re-flash, but I want HKS cams

 

yes you will need to retune as the new cams will flow more air at different rpm's. You may be running lean if you stick with your flash. Remember that properly tuned cams can yield aprox. 30whp extra.

 

Thats what I figured. QUestion when WOT what MPG are we talking about? I ask this because when I go to an all day track event I go through 1 1/2 tanks of gas. I do about 4-5 30 mins rounds around a 1.8 mi road track? I cant imgaine getting crappier gas milage than now.

 

I got about the same mileage at Summit Point (forgot the size). I have cams, pump and 785cc injectors. Your WOT mileage will suffer a little but that's expected with more hp. I still get 27-28 mpg on the highway cruising at 65-70 mph.
